The miller's are comparing babysitting services for their two children.
the babysitter's block charges a rate of $15 an hour per child plus an initial fee of $25 per household.
super sitters charges a flat rate of $20 an hour per child.

it will take 2.5 hours for the hours of service to cost the same.

Step-by-step explanation:

Let L represent the hours of service for which both babysitting services would cost the same.

Let x represent the cost of L hours when using the Babysitter's Block.

Let y represent the cost of L hours when using the Super Sitters.

The Babysitter's Block charges a rate of $15 an hour per child plus an initial fee of $25 per household. This means that the cost of L hours for the two children would be

x = 25 + 30L - - - - - - - - - - - -1

Super Sitters charges a flat rate of $20 an hour per child. This means that the total cost for L hours for the two children would be

y = 40L

To determine the the hours of service for which both babysitting services would cost the same, we would equate x to y. It becomes

25 + 30L = 40L

25 = 40L - 30L = 10L

L = 25/10 = 2.5 hours

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
